being an improvement on and cultivator combined disclosed in] myaplication for patent filed vOctober ,28,"'I916,

The principal objects; of my present vention are, to PIOVldB simple andefiic'ien't' means in the form of'a pair of Wheels a1 ranged attheforward end of the main;

frame of 'the machine, and which means can be readily. operated forguiding the machine in either direction laterally during its forwardmovement and also 'for turning the same completely around withinracompara tively small area; to provide a firm and sub-' stantial supportfor the steering wheels to connect said steering Wheel support to themain frame of the machine so that" the support will swing-throughavertical planeupon a central horizontal axis, and' further, to providesimple and elficient meanswhere by. the steering wheels may be turnedlater-f ally either simultaneously or independently,

thereby making it possibleto readily steer the tractor under allconditions.

slightly.- beljolw .theplane occupied by said I naledtherein are shafts26, each of-which 24 is a tubular shaft 7 wheel 37 which is 30 at therear end of the main frame and in a bearing 3l'at the right hand end offrame 32, theforward end of pinion 33, and the rear wheel 34. Extendingshaft 32 and arranged is a shaft 35, the forwhich carries a bevel endcarrying a hand through this tubular for rotation therein ward end ofwhich carries a Worm wheel 36,.

the same meshing with the corresponding worm wheel 27 which isassociated with the right hand one of the steering wheels 29 and therear end of this shaft 35 carries a hand positioned immediately adjacentto'hand wheel 34.

Positioned on a suitable support which extends upwardly andrearwardlyfrom the rear portion of the main frame of the machine and directed tothe'rear of hand wheels 34 and-3L is an operators seat 38.

J ournaled in suitablebearings 39 on the frame 24" is a transverselydisposed shaft 40, the right hand end of which carries a bevel pinion 41the same meshing with pinion 33 and the left hand end of this shaftcarries a worm wheel 42 which meshes with the corresponding worm wheel27 the latter being associated with the left hand one of the steeringwheels 29.

Loosely connected to the outer ends of frame 24 are links 43, the innerends of which are pivotally connected to the side of frontend frame 21.These links 43 are intended to serve as flexible braces for the ends offrame 24 and to permit it to rock Vertically for a limited distance uponitshorizontal axis 23. Obviously, the connections between the ends ofthese links 43 and mainframe and transverse frame 24 must besufliciently loose to permit said frame 24 to moveivertically for acertain distance.

Mounted on the front portion of the main frame of the machine andpreferably on the 7 left hand side thereof is the motor 44 whichfurnishes the power for driving my improved m'achine, said motor beingpreferably an internal combustion engine, the shaft of which isconnected by a suitable train of gearing to shaft 17, which lattercarries the pinions 20 that mesh with gear wheels 16 on the main drivingwheels of the tractor.

' While my improved tractor is in opera tion, the motion of the engineshaft is transgrasps thehand wheels 34 mitted by a suitable train ofgearing to dif ferential shaft 17 and from thencethrough pinions 20 togear wheels 16, which latter are carried'by the main traction wheels 15.

During the forward movement of the tractor, it is guided by the operatorpositioned on the seat 38 and who simultaneously and 37, whichlatter-are carried by tubular shaft 32 and shaft 35.1 As these shaftsare simultaneously rotated, corresponding movement is simultaneouslyimparted through worm wheels 36 and 42 to worm wheels 27 which arecarried by the upper ends of arms 28 upon which the steering wheels arejournaled. Thus, the steering wheels are simultaneously andcorrespondingly turned to guide the tractor in its forward movement.

In the event that it is desired to turn completely around or through anarc of one hundred eighty degrees and which action would be likely totake place at the end of a field which is being plowed, the operatorlocks either one side or the other of the differential by application ofthe proper brake band on the corresponding drum 19 with the result thatone of the traction wheels 15 is locked and as the engine continues inoperation, the machine will turn around with the vertical center of thelocked wheel as the aXis of turning movement, and during this time, theoperator releases the hand wheels 34 and 37, thereby permitting thesteering wheels 29 to swing freely of their own accord into properposition to accomplish this short turning movement. During this turningmovement, the members 28 to which the steering wheels 29 are journaledcan move independently of each other by virtue of the fact that they arenot positively connected and the shaft 35 within the hollow shaft 32enables the steering connections to the front wheels tooperateindependently.

During the movement of the tractor over comparatively rough ground,frame 24 which carries the steering wheels can swing vertically on itshorizontal pivot for a limited distance, thereby accommodating thesteering wheels to the unevenness of the ground and in the event thateither one of the steering wheels encounters a rut or hole and it isdesired to shift said wheel laterally to assist the tractor in itsforward movement, said wheel can be actuated by a manipulation of theproper hand wheel 34 or 3 It will be readily understood that minorchanges in the size, form and construction of the various parts of myimproved tractor can be made and substituted for those herein shown anddescribed, without departing from the spirit of my invention, the scopeof which is set forth in the appended claims.
